RE: Dell T3400 orange blinking light in power button

Blinking Amber power button is Bad Power supply.   Solid Amber power button is Dead motherboard.  T3400 with X38 Express Chipset 

525W Active Power Factor Correction (APFC) power supply.

M1J3H, 7JVXX, D525AF-01

PSU may be bad or USB Ports may be damaged creating a short on a main power rail. (PS_ON asserted, PS_PWRGOOD not asserted)
